Basic Concepts of Motorcycle Mechanics




In this section, we will review some of the basic concepts of motorcycle mechanics that are essential for understanding how motorcycles work and how to repair them. We will focus on the four main systems that make up a motorcycle: the engine, the transmission, the chassis and suspension, and the braking system. We will also explain how each system works and what are its main components and functions.


The Four-Stroke Engine Cycle




The engine is the heart of a motorcycle. It is the source of power that propels the motorcycle forward and enables it to perform various functions. The most common type of engine used in motorcycles is the four-stroke engine, also known as the four-cycle engine. This type of engine uses gasoline as fuel and operates by converting the chemical energy of the fuel into mechanical energy through a series of four steps: intake, compression, combustion, and exhaust.


The intake step occurs when the piston moves down from the top of the cylinder (top dead center or TDC) to the bottom of the cylinder (bottom dead center or BDC), creating a vacuum that sucks in a mixture of air and fuel through an intake valve that is open. The compression step occurs when the piston moves up from BDC to TDC, compressing the air-fuel mixture in preparation for ignition. The combustion step occurs when the piston reaches TDC and a spark plug ignites the compressed air-fuel mixture, creating a powerful explosion that pushes the piston down with great force. This is the step that produces mechanical work from the engine to turn the crankshaft. The exhaust step occurs when the piston moves up from BDC to TDC again, expelling the burned gases through an exhaust valve that is open.


The four-stroke engine cycle is repeated for each cylinder in the engine. The number of cylinders in a motorcycle engine can vary from one to six, depending on the size and performance of the motorcycle. The more cylinders an engine has, the more power it can produce, but also the more fuel it consumes and the more complex it becomes.


The main components of a four-stroke engine are:



  • The cylinder: The cylindrical chamber where the piston moves up and down and where combustion takes place.



  • The piston: The cylindrical part that fits inside the cylinder and moves up and down due to combustion pressure.



  • The connecting rod: The rod that connects the piston to the crankshaft.



  • The crankshaft: The shaft that converts the up-and-down motion of the piston into rotational motion.



  • The spark plug: The device that produces a spark to ignite the air-fuel mixture in the cylinder.



  • The intake valve: The valve that opens and closes to allow air-fuel mixture into the cylinder during intake.



  • The exhaust valve: The valve that opens and closes to allow burned gases out of the cylinder during exhaust.



  • The camshaft: The shaft that controls the opening and closing of the valves through cam lobes.



  • The timing chain: The chain that synchronizes the rotation of the crankshaft and camshaft.



To maintain and troubleshoot a four-stroke engine, you need to check and adjust various parameters such as:



The Transmission System




The transmission system is the system that transfers the power from the engine to the rear wheel of the motorcycle. It consists of a series of gears that can be changed to alter the speed and torque of the motorcycle according to the riding conditions. The transmission system also includes a clutch that allows the rider to disengage and engage the engine from the transmission, and a drive system that connects the transmission to the rear wheel.


The most common type of transmission system used in motorcycles is the manual transmission, also known as the sequential transmission. This type of transmission requires the rider to manually shift gears by using a foot lever and a hand clutch. The foot lever is located on the left side of the motorcycle and is used to move up or down through the gears. The hand clutch is located on the left handlebar and is used to disengage and engage the engine from the transmission. The rider has to coordinate the use of both the foot lever and the hand clutch to smoothly shift gears without stalling or damaging the engine.


The manual transmission has a fixed number of gears that can vary from four to six, depending on the size and performance of the motorcycle. The gears are arranged in a sequential order, meaning that they can only be accessed in a specific sequence. For example, a five-speed manual transmission has five gears that can be shifted in this order: 1-N-2-3-4-5, where N stands for neutral. Neutral is a position where no gear is engaged and the engine is disconnected from the transmission. Neutral can be found between first and second gear by slightly moving the foot lever up or down from either gear.


The main components of a manual transmission are:



  • The gearset: The set of gears that provide different gear ratios for different speeds and torques.



  • The shift drum: The cylindrical part that rotates to align different gears with each other.



  • The shift forks: The parts that slide along grooves on the shift drum and move different gears into position.



  • The shift lever: The foot-operated lever that rotates the shift drum through a linkage.



  • The clutch: The device that disengages and engages the engine from the transmission through friction plates.



  • The clutch lever: The hand-operated lever that controls the clutch through a cable or a hydraulic system.



To maintain and troubleshoot a manual transmission, you need to check and adjust various parameters such as:



The Braking System




The braking system is the system that allows the rider to slow down or stop the motorcycle by applying friction to the wheels. It consists of a set of brake levers, brake lines, brake calipers, brake pads, and brake discs or drums. The braking system can be divided into two types: disc brakes and drum brakes.


Disc brakes are the most common type of brakes used in motorcycles today. They work by squeezing a pair of brake pads against a metal disc that is attached to the wheel. The friction between the pads and the disc creates a braking force that reduces the speed of the wheel. Disc brakes are more effective, responsive, and durable than drum brakes. They also perform better in wet conditions and dissipate heat faster.


Drum brakes are an older type of brakes that are still used on some motorcycles, especially on the rear wheel. They work by expanding a pair of brake shoes inside a metal drum that is attached to the wheel. The friction between the shoes and the drum creates a braking force that reduces the speed of the wheel. Drum brakes are cheaper, simpler, and lighter than disc brakes. However, they are also less powerful, less consistent, and more prone to fading and overheating.


The main components of a braking system are:



  • The brake lever: The hand-operated lever that controls the braking action by applying hydraulic pressure to the brake lines.



  • The brake line: The tube that carries hydraulic fluid from the brake lever to the brake caliper.



  • The brake caliper: The device that holds and moves the brake pads against the brake disc or drum.



  • The brake pad: The material that contacts the brake disc or drum and creates friction.



  • The brake disc or drum: The metal part that rotates with the wheel and provides a surface for friction.



To maintain and troubleshoot a braking system, you need to check and adjust various parameters such as:



  • The brake fluid: The hydraulic fluid that transfers pressure from the brake lever to the brake caliper. It needs to be replaced periodically to prevent contamination and degradation.



  • The brake pad: The material that wears out over time and needs to be replaced when it reaches a minimum thickness.



The Electrical System




The electrical system on a motorcycle is the system that provides power to the ignition system, lights, and other accessories. It consists of a battery, a charging system, an ignition system, and a wiring harness. The electrical system can be divided into two types: direct current (DC) and alternating current (AC).


Direct current (DC) is the type of current that flows in one direction only. It is produced by the battery and used by most of the electrical components on the motorcycle, such as the lights, horn, indicators, etc. The battery is a device that stores electrical energy and releases it when needed. Most motorcycles have a 12-volt battery, which means it produces 12 volts of power. The battery needs to be charged regularly to prevent it from losing its capacity and performance.


Alternating current (AC) is the type of current that changes its direction periodically. It is produced by the charging system and used by some of the electrical components on the motorcycle, such as the ignition system. The charging system is a device that converts mechanical energy into electrical energy and keeps the battery charged. It consists of an alternator or a generator, a voltage regulator or a rectifier, and a wiring harness. The alternator or generator is a device that produces AC by spinning a coil of wire inside a magnetic field. The voltage regulator or rectifier is a device that converts AC into DC and regulates the voltage to prevent overcharging or undercharging the battery. The wiring harness is a set of wires that connects all the electrical components to each other and to the battery.


The ignition system is the system that ignites the air-fuel mixture in the engine cylinders and produces combustion. It consists of an ignition switch, an ignition coil, a spark plug, and a wiring harness. The ignition switch is a device that turns on or off the ignition system by using a key or a button. The ignition coil is a device that transforms low voltage DC from the battery into high voltage AC for the spark plug. The spark plug is a device that creates a spark across a gap to ignite the air-fuel mixture in the cylinder. The wiring harness is a set of wires that connects all the ignition components to each other and to the charging system.


The main components of an electrical system are:



  • The battery: The device that stores and releases electrical energy.



  • The charging system: The device that converts mechanical energy into electrical energy and keeps the battery charged.



  • The ignition system: The device that ignites the air-fuel mixture in the engine cylinders and produces combustion.



  • The wiring harness: The set of wires that connects all the electrical components to each other and to the battery.



To maintain and troubleshoot an electrical system, you need to check and adjust various parameters such as:



  • The battery voltage: The measure of electrical potential difference between the positive and negative terminals of the battery. It should be around 12 volts when fully charged and not drop below 10 volts when starting.
